With a strong emphasis on quality, precision, and performance, the company caters to essential industries such as aerospace, power generation, automotive, and high-temperature processing. Brian Fasteners designs Stainless Steel 422 Nuts specifically for demanding applications where strength, thermal stability, and oxidation resistance are crucial. Committed to excellence and adhering to global standards, the company provides durable fastening solutions tailored to the unique needs of complex industrial operations.
Stainless Steel 422 Nuts are crafted from a martensitic stainless steel alloy that contains about 12% chromium, 0.2–0.4% carbon, along with small amounts of molybdenum and vanadium. This blend results in a remarkable combination of high tensile strength (up to 895 MPa), yield strength around 655 MPa, and solid oxidation and creep resistance at elevated temperatures. These nuts maintain their mechanical integrity even under thermal and mechanical stress, making them perfect for high-heat environments. Additionally, Stainless Steel 422 can be heat-treated to further boost strength and hardness while still offering moderate corrosion resistance.
